When Do I Use Than And Then

When do I use than and then is a common question for anyone polishing their English writing. Though the two words look and sound similar, they serve completely different grammatical purposes. Knowing when to choose than versus then helps you avoid embarrassing mistakes and makes your sentences clearer and more professional. This guide breaks down the rules, offers easy‑to‑remember tips, and provides practice so you can confidently pick the right word every time Worth keeping that in mind..

Understanding the Basics

Than is a conjunction used for comparisons. It links two items that are being measured against each other in terms of size, amount, quality, or any other attribute.
Then is an adverb (sometimes also a noun or adjective) that refers to time or sequence. It tells the reader when something happened or what comes next in a series of events.

A quick mental check: if you are comparing, think than; if you are talking about time or order, think then.

When to Use “Than”

Use than whenever you are setting up a comparison. The structure usually follows the pattern:

[Subject] + [verb] + [adjective/adverb] + than + [comparison target]

Examples

• She is taller than her brother.
• This recipe requires less sugar than the one I used last week.
• He runs faster than anyone on the team.
• I would rather stay home than go out in the rain.

Special Cases

1. Comparative adjectives ending in -er (bigger, smarter, happier) always pair with than.
2. Comparative adverbs (more quickly, less often) also need than.
3. Pronoun choice after than can be tricky. Formal writing prefers the subject form when the verb is implied:
   • She is smarter than I (am).
     In informal speech, many people say than me, which is widely accepted but considered less formal.
4. Comparisons with “as … as” do not use than; they use as instead:
   • She is as tall as her sister.

Quick Tip

If you can replace the word with “compared to” and the sentence still makes sense, you need than.

• She is taller compared to her brother. → *She is taller than her brother.

When to Use “Then”
